Carly Fiorina, the former Hewlett-Packard CEO who may be a GOP presidential candidate, painted Hillary Clinton as a hypocrite and questioned her effectiveness during a speech Thursday at the Conservative Political Action Conference. "Mrs. Clinton, name an accomplishment," Fiorina said.

"She tweets about women’s rights in this country and takes money from governments that deny women the most basic human rights," Fiorina said, according to numerous reports. "She tweets about equal pay for women but won’t answer basic questions about her own offices’ pay standards -- and neither will our president."

"Hillary likes hashtags," Fiorina added. "But she doesn’t know what leadership means."

This is not the first time Fiorina, a failed U.S. Senate candidate, has blasted the Democrats’ unofficial presidential front-runner. "Like Hillary Clinton, I too have traveled thousands of miles around the globe,” Fiorina said at the Iowa Freedom Summit last month. “But unlike her, I've actually accomplished something.”

Fiorina also slammed the Clinton Global Initiative, which seems to be developing into an area of vulnerability for Clinton, politically.

The Washington Post reported that more than half of the $5 million donations the Clinton foundation received came from foreign donors. The New York Times editorial board called for Clinton to ban foreign donors last week, just as the nonprofit did when Clinton was confirmed as secretary of state in 2009. CGI lifted that ban shortly after Clinton left the Obama cabinet back in 2013, according to reports in the Wall Street Journal.

"Please explain why we should accept that the millions and millions of dollars that have flowed into the Clinton Global Initiative from foreign governments doesn’t represent a conflict of interest," Fiorina said on Thursday.

Fiorina has not formally declared her candidacy. Two weeks ago, she formed a political action committee that will enable her to raise money for a run.
